PAUL R. TAPPAN, OF MANSFIELD, OHIO.

BURNER.

Application filed June 5, 1915.

To all whom it may concern. 4

Be it known that I, PAUL R. TAPPAN, a citizen of the United States ofAmerica, residing at Mansfield, in the county of Richland and State ofOhio, have invented certain new and useful Improvements in Burners, ofwhich the following is a specification.

This invention relates to new and useful improvements in burners andmoreparticularly to a gas burner, and it has for its primary object tosave gas and be efficient in operation throughout.

One of the objects of this invention is to provide a means of preventingthe gaseous mixture from popping back in the burner and blowing out theflame when the flow of gas is decreased (thereby preventing the propercombustion thereof) which comprises the use of a member which obstructsthe passageway of the gaseous mixture, said member preferably consistingof a sheet of foraminous material used in combination with means forenlarging the area of the passageway of the mixture at the point of theinsertion in the passageway of the foraminous material said materialcompensating and allowing for the space of the passageway taken up bythe walls forming the openings in the mesh of the gauze, screen or otherforaminous plate or material.

A further object is to thoroughly atomize the mixture to provide forproper combustion.

Other objects will be set forth hereinafter and those features ofconstruction, arrangements and combinations of parts to be protectedwill be defined in a succinct manner in the annexed claims.

For a full understanding of the invention, reference is had to thefollowing specification, and the accompanying drawing wherein likecharacters of reference designate corresponding parts, and Figure'l is afragmentary top plan of the top of a stove embodying the presentinvention in its preferred form; Fig. 2 illustrates the same in sideelevation with part in section showing the insertion of sheet offoraminous material between the elbow burner" which is formed of twoparts; and Fig. 3 is a plan view of the elbow burner showing theforaminous material and air and gas mixing pipe applied thereto.

Referring more particularly to the drawing, numeral 1 designates the topof the I Specification of Letters Patent.

stove, 8 the gas and air supply pipe and 8 a disk having radial arms 4:projecting there from and resting upon the stove top at the edge of thestove opening 5.

Reference numeral 6 represents the gas controlling valve adapted forregulating the supply from the pipe 2 to a conventional type of airmixer 7 which is carried on the outer end of air and gas supply pipe 8.

Threaded on the inner end of the pipe 8 is the gas burner 9 which is ofelbow shape and has an upwardly directed tip 10 disposed immediatelybelow the disk 3 so that the apex 12 of the inner cone 13 of the flameissuing from the single, large opening 11, which is formed in jet or tip10, will reach or touch the bottom or under side of the disk withoutleaving any air space between the flame and disk.

The elbow burner 9 is composed of two parts and a sheet of foraminousmaterial 9 is interposed therebetween and is preferably held in place bythe bolts 9 which pass through the ears 9 The area 9 of the elbow isgradually enlarged from the end 9 of the pipe 8 to compensate for thespace taken up by the walls forming the opening in the foraminousmaterial. When the gaseous mixture passes through the foraminousmaterial, it is thoroughly atomized.

In this connection it will be noted that the burner is much easier toclean than the common type of burner because the latter has a pluralityof small apertures whereas one large opening 11 is provided in the body9. Furthermore, in a burner of this type, it is well lmown that the apexof the inner cone of the flame is the hottest part thereof, and hotterthan the outer flame part represented by arrows 14, which surrounds cone13. Therefore, the disk 3 is in direct contact with the hottest part ofthe flame.

The disk retains the heat radiation of the flame cone 13 in closecontact with a superposed vessel and also performs the function of aguard in preventing foreign matter from entering the burner opening 11as when the cooking vessel or utensil boils over. The outer part of theflame of the burner spreads over the entire bottom of the vessel therebyplacing the same in a hotter zone than if air was allowed between theflame and the bottom of the vessel such as when the flame does not touchthe latter. The disk further serves as a baffle to the flame to andreplace, and has been tested as to its increased efliciency and gassaving" The loss of heat resulting when using a gas stove equipped withthe ordinary burners is due to imperfect combustion and the vessel notbeing in contact with the flame. Both of these undesirable conditionsare effectually overcome by the present device which results in a savingof gas and a very pronounced increase in efiiciency.

What is claimed is:

' 1. A burner including a hollow body formed with an inlet and anoutlet, the sectional dimensions of the interior of the burner beinggradually increased from the inlet and outlet toward the central portionof the burner, and aplate of foraminous material secured within theburner at the point of maximum interior dimensions, said plate beinginclined with respect tothe plane of both the inlet and outlet.

2. A burner constructed in two parts, having an inlet and an outletarranged at an angle to each other, and a foraminous plate arrangedwithin the burner and at an angle to the inlet and outlet and midwaytherebetween.

3. A burner including approximately duplicate sections, each having afuel opening at one end, and a larger opening at the opposite end, theedge of the section at the end including the larger opening beingarranged at an angle to the edge of the section including the fuelopening, means for securing the sections with the edges of the endsincluding the larger openings in adjacent relation, and a foraminousplate held between such edges.

In testimony whereof I afiix my signature in presence of two witnesses.
